 After holding the land for four or five generations the Ngāti Mamoe in their turn were attacked and finally subjugated by another wave of invaders from the north.These were the Ngāi Tahu, who, although originally settling in the Poverty Bay district on their arrival in canoes, had subsequently moved southwards.In 1627, the Ngāi Tahu had their chief settlement on the shores of Wellington harbour at Hataitai, but began to move over the northern parts of the South Island, which was then the territory of the Ngāti Mamoe.
